CHAIR.

SPECIFICATION forming part of Letters Patent No. 733,857, dated July 14, 1903. Application filed December 22,1902. Serial No. 136,237. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH A. MANAHAN, a citizen of the United States, residing in Man hattan borough, New York city, in the county and State of New York, have invented new and useful Improvements in Chairs, of which the following is a specification.

This invention relates to certain improvements in chairs having adjustable backs; and the invention resides in the novel features of construction set forth in the following specification and claim and illustrated in the an- .nexed drawings, in which Figure l is a detail view of a lever. Fig. 2 shows a face and an edge viewof the bracket Fig. 3 shows a spring. Fig. 4 shows a face and an edge View of the guide-bracket for the lever. Fig. 5 showsa perspective and an end view of the spring for holding the lever in looking position. Fig. 6 shows a chair embodying this invention.

In the drawings the chair is shown having a movable or hinged back 0. A regulatinglever A is hinged or fulcrumed to the back and has its free end extended forward under the arm P of the chair. A guide-bracket K for the lever is secured to the arm P. The lever has a rack portion B at its lower edge, and the pin L in bracket K forms a tooth or catch portion to coact with the lever-teeth. The spring M at the chair-arm acts on the lever to press its rack portion to engagement or tolock with the lever guide-bracket K or its cross-pin L. The fulcrum of the lever is formed by a bracket F, having screw-holes H for connection with the chair-back, and a reduced or shouldered pivot portion G, with an t 1 eye I. The lever being pushed onto pivot or fulcrum G up to the shoulder formed by body part F, the spring J is hooked or connected be forced back against the tension of the lift- I ing-spring J to the desired inclination. The lever being then freed, the spring M presses the lever downward to engage or look with the bracket and hold the back in position.

The lever A is suitably enlarged, as seen at C, to allow for the formation of rack B, and

the lever part D has the eye E to slip onto fulcrum-pin G. The spring M has its end N suitably shaped and grooved to sit on or straddle the lever A and remain in engagement therewith. The spring J when hooked into eye I holds the lever in place, so that it will not slip off the fulcrum.

What I claim as new, and desire to secure by Letters Patent, is

A chair having a movable back, a shouldered and perforated bracket secured to the back, a lever slipped onto the bracket to sit against the shoulder, a spring hooked into the eye of the bracket to hold the lever in I JOSEPH A. MANAHAN.
